This paper challenges the presumed triumph of laboratory life in the history of twentieth-century biomedical research through an exploration of the relationships between laboratory, clinic, and field in the regional understanding and treatment of allergy in America. In the early establishment of allergy clinics, many physicians opted to work closely with botanists knowledgeable about the local flora in the region to develop pollen extracts in desensitization treatments, rather than rely upon pharmaceutical companies that had adopted a principle of standardized vaccines (...) beholden to bacteriology that gave no thought to the particularities of place where their products were to be sold. Natural historical sciences like plant ecology and systematics furnished important knowledge, resources, and practices in establishing a medical marketplace for allergy in America. And botanists similarly profited from biomedicine and allergic bodies in extending their network of knowledge about the plant world. (shrink)

An allergy is commonly understood to be an overreaction of the immune system to harmless substances that are misrecognised as foreign. This concept of allergy as an abnormal, misdirected immune response—a biological fault—stems from the idea that the immune system is an inherently defensive operation designed to protect the individual through an innate capacity to discriminate between the benign and toxic, or self and nonself. However, this definition of allergy represents a radical departure from its original formulation. Literally meaning ‘altered (...) reactivity’, the term was coined in 1906 by Austrian paediatrician Clemens von Pirquet, to describe the fundamentally mutable nature of the immune response.This paper argues that the conventional interpretation of allergy-as-pathology derives from specific concepts of ‘organism’, ‘response’, and ‘normal’ immune function that have—for over a century—governed the perception and study of immune phenomena within immunology. Through an examination of Louis Pasteur’s conceptualisation of the host body/microorganism relationship, I argue that immunology is founded on a view of the organism as a discrete, autonomous entity, and on a concomitant notion of the immune response as essentially reactive. Revisiting the concept of ‘altered reactivity’, this paper points to the fact that allergy was initially posited as a general theory of immune responsiveness and, importantly, one that poses a significant challenge to orthodox notions of immunopathology. It suggests that Pirquet’s unique view of immune responsiveness presents an account of organismic or biological identity that encapsulates, rather than reduces, its ecological complexity. (shrink)

During the 1940s and 1950s, the Australian microbiologist F. Macfarlane Burnet sought a biologically plausible explanation of antibody production. In this essay, we seek to recover the conceptual pathways that Burnet followed in his immunological theorizing. In so doing, we emphasize the influence of speculations on individuality, especially those of philosopher Alfred North Whitehead; the impact of cybernetics and information theory; and the contributions of clinical research into autoimmune disease that took place in Melbourne. We point to the influence of (...) local experimental and intellectual currents on Burnet’s work. Accordingly, this essay describes an arc distinct from most other tracings of Burnet’s conceptual development, which focus on his early bacteriophage research, his fascination with the work of Julian Huxley and other biologists in the 1920s, and his interest in North Atlantic experimental investigations in the life sciences. No doubt these too were potent influences, but they seem insufficient to explain, for example, Burnet’s sudden enthusiasm in the 1940s for immunological definitions of self and not-self. We want to demonstrate here how Burnet’s deep involvement in philosophical biology – along with attention to local clinical research – provided him with additional theoretic tools and conceptual equipment, with which to explain immune function.
